The '''[[Imperial Trans-Antarctic Expedition]]''' (1914–17), also known as the '''Endurance Expedition''', is considered the last major expedition of the Heroic Age of [[Antarctic]] Exploration. Conceived by Sir [[Ernest Shackleton]], the expedition was an attempt to make the first land crossing of the Antarctic continent.

Wesley E. LeMasurier is an igneous petrologist/volcanologist who specializes in the study of Cenozoic volcanoes in the Marie Byrd Land region of Antarctica. He was responsible for geological research around many of Westarctica's volcanic mountains. Mount LeMasurier was named in his honor.

Dr. LeMasurier's work includes studying the origin and evolution of Cenozoic volcanic rocks, the nature of the tectonic environment of volcanism, and the volcanic record of glacial history. In 1990, after conducting a survey of Mount Berlin, he declared the volcano to be "potentially active." Later, in 1994, during field work around Mount Siple, Dr. LeMasurier knocked off a piece of rock from the mountain and sent it to Ruth Siple, the widow of Paul A.
